Answer:

24 marbles

Step-by-step explanation:

P( purple) = 2/3 = purple/total

2/3 = 16/total

Using cross products

2 * total = 3 *16

2 * total = 48

total = 24

There are 24 marbles

Please help on this math question!!

katrin2010 [14]

Answer:

x = 49

Step-by-step explanation:

The third side of the largest of the inner triangles:

= $\sqrt{(7\sqrt{(33)^{2} }- (33)^{2}$

= $\sqrt{528} =\sqrt{(16)(33)} =4\sqrt{33}$

The side that continues next to 33: x -33

Applying similarity property on right triangles:

$\frac{33}{4\sqrt{33} } =\frac{4\sqrt{33} }{x-33}$

$(33)(x-33)=(4\sqrt{33} )^{2}$

$33x-1089=528$

$33x=528+1089$

$x=\frac{528+1089}{33} =49$

Hope this helps

The probability that the student has a part-time job, given that they have a cell phone is 5/8

<h3>What is probability</h3>

Probability is the likelihood or chance that an event will occur.

Given the following parameter:

Total student = 80%
Part-time jobs = 45%
Those with both a cell phone and a part-time job = 30%

Student will cellphone only = 80 - 30 = 50%

The probability that the student has a part-time job, given that they have a cell phone is 50/80 = 5/8

In an experiment, there are n independent trials. For each trial, there are three outcomes, A, B, and C. For each trial, the pro

Mekhanik [1.2K]

Answer:

(B) No. A binomial probability model applies to only two outcomes per trial.

Step-by-step explanation:

The binomial probability is the probability of having $x$ sucesses on $n$ repeated trials of an experiment that can only have two outcomes. This is why it is called the binomial probability.

Since in our problem there are three possible outcomes, the binomial probability cannot be used.

The correct answer is (B)

(B) No. A binomial probability model applies to only two outcomes per trial.
